About Sutherland's Ice Plant

Delosperma sutherlandii · also called Sutherland's Delosperma, Hardy Pink Ice Plant · houseplant

Sutherland's Ice Plant is a hardy South African succulent producing a profusion of vivid pink-purple daisy-like flowers from spring to autumn. Its fleshy, cylindrical leaves form dense, low mats suited to rock gardens and sunny containers. One of the hardier Delosperma species, tolerating light frosts. Non-toxic and pet-safe.

Mature size: 5-10 cm tall, spreading 20-40 cm wide

Watch for — Root rot in wet winters: Cold, wet soil in winter is the most common cause of plant death. Ensure excellent drainage, and in very wet climates consider a gravel mulch or moving containers under cover.

How to tell sutherland's ice plant needs repotting

Repotting on a calendar is less reliable than reading the plant. For sutherland's ice plant, watch for these signs:

Roots growing out of the drainage holes, or the rootball lifting the plant proud of the rim.
Soil that has shrunk away from the pot sides and no longer holds water.
The pot is unstable because the plant has grown top-heavy.
Old, compacted, broken-down mix that stays wet too long — for a succulent that is a rot risk, so refresh it even if the pot size is fine.

How often to repot sutherland's ice plant

Every 2–3 years, into bone-dry mix. Sutherland's Ice Plant's growth habit — dense, mat-forming, low-growing succulent perennial — sets the pace. Sutherland's Ice Plant is a hardy South African succulent producing a profusion of vivid pink-purple daisy-like flowers from spring to autumn. Its fleshy, cylindrical leaves form dense, low mats suited to rock gardens and sunny containers. One of the hardier Delosperma species, tolerating light frosts. Non-toxic and pet-safe.

What size pot to step sutherland's ice plant up to

Use a pot only one size up — or even the same pot with fresh gritty mix if the roots have room. Sutherland's Ice Plant stores water and rots in a large pot of slow-drying soil. A tight terracotta pot that dries fast is far safer than a generous plastic one. Never up-pot a succulent by several sizes.

The best time of year to repot sutherland's ice plant

Spring or summer, while sutherland's ice plant is in active growth and warm, is best — roots recover fastest then, and the plant is not sitting in cool damp soil. Avoid repotting a succulent in winter dormancy.

Step-by-step: repotting sutherland's ice plant

Repot dry. Do not water sutherland's ice plant for several days first. Working with dry roots and dry mix dramatically lowers the rot risk for a succulent.
Pick a snug, fast-draining pot. Choose terracotta one size up at most, with a drainage hole. Have gritty sharply draining cactus or succulent mix with extra grit ready.
Tip it out and clean the roots. Slide the plant out, crumble off the old soil, and trim any black, mushy or dead roots with clean snips.
Pot into dry mix. Set sutherland's ice plant at its original depth in dry gritty mix, firming gently. Do not bury the stem deeper than it was.
Wait a week before watering. Leave it completely dry and out of harsh sun for about 7 days so any damaged roots callus. Only then water lightly.

Aftercare

Keep sutherland's ice plant completely dry and out of fierce sun for about a week so any nicked roots callus before they meet moisture; watering a freshly repotted succulent is the classic way to rot it. Then resume the normal lean, dry rhythm. Do not fertilise for about 3 weeks — fresh mix already carries nutrients and feeding freshly disturbed roots scorches them.

The right soil mix for sutherland's ice plant

Sutherland's Ice Plant wants sharply draining cactus or succulent mix with extra grit. Combine cactus compost with 40-50% coarse horticultural grit or perlite. This species, like all Delosperma, is intolerant of prolonged soil moisture. Neutral to slightly alkaline pH (6.5-7.5) is ideal. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting sutherland's ice plant — frequently asked questions

How often should you repot sutherland's ice plant?

Every 2–3 years, into bone-dry mix for sutherland's ice plant. Repot sutherland's ice plant every 2–3 years into a snug pot of sharply draining cactus or succulent mix with extra grit, ideally in spring or summer. Let it sit in dry soil and do not water for about a week afterwards so any nicked roots can callus. Over-potting and watering straight away is what rots succulents.

What size pot does sutherland's ice plant need?

When is the best time of year to repot sutherland's ice plant?

Should you water sutherland's ice plant after repotting?

No — not straight away. Repot sutherland's ice plant into dry mix and wait about a week before the first watering so any damaged roots callus over. Watering a freshly repotted succulent is the single most common way to rot one.

Should you fertilise sutherland's ice plant after repotting?

Not immediately. Wait about 3 weeks after repotting sutherland's ice plant. Fresh mix already contains nutrients, and feeding freshly cut or disturbed roots burns them. Resume your normal feeding routine once you see new growth.
